AdTool.FenomenGame is an example of an Adware application. This software is not to be mistaken with a virus or a Trojan application, AdTool.FenomenGame is regarded by many experts as a "potentially unwanted program" (PUP). PUPs are applications that a security, or privacy-minded computer user may want to be informed of and, in most instances, may feel the need to remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, and may even compromise the privacy of the infected system. AdTool.FenomenGame is a program that facilitates the delivery of advertising content to the system user and in some cases may gather information from the user's computer, including information related to Internet browser usage and other computer habits. AdTool.FenomenGame may monopolise the computer system’s resources and is largely responsible for the countless pop-up advertisements the user will be bombarded with. AdTool.FenomenGame is often bundled with or embedded within freeware programs like such as clocks, messengers, alerts, weather, and so on. It is best to remove this dubious application as soon as it has been detected within a computer system.
